将ID添加到Google地图标记

我试图让当前标记有一个信息窗口，并且只有5个标记标记在地图上的时间（4没有信息窗口和1）

我如何添加一个id到每个标记，以便我可以删除和关闭信息窗口

这是我用来设置标记的函数：

function codeAddress（address，contentString）{ var infowindow = new google.maps.InfoWindow（{ content：contentString }）; if（geocoder）{ geocoder.geocode（{'address'：address}，function（results，status）{ if（状态== google.maps.GeocoderStatus.OK）{ map.setCenter（results [0] .geometry.location）; var marker = new google.maps。标记（{ map：map， position：results [0] .geometry.location }）; infowindow.open（map，marker）; $ b $}其他{ alert（由于以下原因，地理编码不成功：+ status; } }）; }

}

解决方案

JavaScript是一种动态语言。您可以将其添加到对象本身。

var marker = new google.maps.Marker（markerOptions）; marker.metadata = {type：point，id：1};

另外，因为所有v3对象都会扩展 MVCObject（） 。您可以使用：

marker.setValues（{type：point，id：1}）; //或 marker.set（type，point）; marker.set（id，1）; var val = marker.get（id）;

I have a script that loops and adds markers one at a time.

I am trying to get the current marker to have an info window and and only have 5 markers on a map at a time (4 without info windows and 1 with)

How would I add an id to each marker so that I can delete and close info windows as needed.

This is the function I am using to set the marker:

function codeAddress(address, contentString) { var infowindow = new google.maps.InfoWindow({ content: contentString }); if (geocoder) { geocoder.geocode( { 'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); infowindow.open(map,marker); } else { alert("Geocode was not successful for the following reason: " + status); } }); }

}

解决方案

JavaScript is a dynamic language. You could just add it to the object itself.

var marker = new google.maps.Marker(markerOptions); marker.metadata = {type: "point", id: 1};

Also, because all v3 objects extend MVCObject(). You can use:

marker.setValues({type: "point", id: 1}); // or marker.set("type", "point"); marker.set("id", 1); var val = marker.get("id");
